本論文最主要的目的是建立以數位信號處理器(DSP)為基礎，而能夠應用於碟形永磁式線性同步電動機的最佳效率控制架構。從推導電動機的數學模型，並發展出最佳效率之策略，再以數位信號處理器及週邊電路來完成穩態實驗數據，進而分析電動機運轉於最佳效率時，如何設定定子線圈繞組的電壓觸發位移角度，並以此資料建立程式的資料庫，作為動態實驗時操作的依據。最後，則以實驗來實現電動機的最佳效率控制及驗證理論分析。

This objective of this thesis is to establish the whole structure for optimal efficiency operations of a disc permanent magnet linear synchronous machine (DPMLSM) based on a digital signal processor (DSP). The thesis is to present the derivation algorithm and strategy of achieving optimal efficiency operations. To fulfill the operational requirements the theoretical basis and experimental database will first be developed, along with the constructions of adequate digital processor-base control and peripheral circuits. Hence the appropriate trigger angles of machine stator phase windings can be advised, and the control objectives of the DPMLSM under steady-state as well as dynamic conditions can be achieved.
